Coombe mine water: pilot-scale treatment scheme 

We are pleased to be able to bring you an update on our proposed treatment scheme near Coombe, which will begin cleaning up the 14km of river that is polluted by water coming out of the former Great Dowgas and St Austell Consols mines.

The project is part of the Water and Abandoned Metal Mines (WAMM) programme, a partnership between the Coal Authority, the Environment Agency and the Department for Environment, Food and Rural Affairs, that was set up to tackle water pollution from historical metal mines.

The proposed pilot-scale treatment scheme was given planning permission by Cornwall Council in February 2020. Since then we have been working on the final design details but, in common with many organisations, our progress has been disrupted by COVID-19.

We are now in a position to access the site and progress, over the next few months we will:
• carry out a geophysical survey to identify if any action is needed to deal with risks from buried structures or voids near the access track
• erect fencing on the site to manage the risks from known mineshafts
• look to appoint a contractor to start building the scheme in spring 2021
• ensure that we deal with all planning conditions laid out by Cornwall Council before starting to build the scheme
• if COVID-19 restrictions allow, we intend to hold another public event in Coombe in early 2021 to explain how we will minimise impacts on the village and surrounding area when we are building the scheme
• a virtual event will be arranged if face to face meetings are not possible

Safe working practices
Our top priority is to protect your welfare as well as those undertaking the project. Please be assured that our contractors and staff will continue to follow all government guidance, including social distancing measures, and normal health and safety practices.
